Final answer:
The muscle that does not originate on the scapula is either the pectoralis major or the latissimus dorsi, as they originate on the axial skeleton.
Step-by-step explanation:
The student's question is asking for the muscle that does not originate on the scapula. All muscles mentioned, except the pectoralis major and latissimus dorsi, which originate on the axial skeleton, have their origin on the scapula. Hence, either of these could be the exception the question refers to. The deltoid, subscapularis, supraspinatus, infraspinatus, teres major, teres minor, and coracobrachialis all originate on the scapula. The scapula is a flat, triangular bone that supports these muscles and provides a stable base for the movements of the shoulder joint.
